Apex Tactical 107003 Action EnhancementBlack Drop-In Fits S&W SD9/40/357, SDVE9/40/357, Sigma

The Apex SD Polymer Action Enhancement Trigger directly replaces the factory hinged trigger with a solid body polymer trigger with a center-mounted pivoting safety. The rounded face of the trigger provides a smooth comfortable surface for the shooter's finger. The trigger also reduces pre-travel by approximately 20% and over-travel by 10% when compared to the factory trigger and is perfect for use in SD and Sigma pistols already equipped with an Apex SD or Sigma Spring Kit. The trigger also works as a standalone component.
